In this talk, we mainly introduce our proposed new research direction: Digital Twin Edge Networks (DITEN). We first present the concept and model related to Digital Twin (DT) and DITEN. Then, we focus on new research challenges and results when machine learning is exploited in DITEN, including federated learning, deep reinforcement learning and transfer learning. Edge association and DT mobility, as unique research questions, will be defined and analyzed. We are also expecting that the talk will help the audience understand the future development of edge computing, e.g., digital twin edge networks in the context of Metaverse.

In recent years, 3D human activity recognition (HAR) has become an important topic in human-computer interaction (HCI). To improve the privacy of users, there is considerable interest in techniques without using a video camera. Various radio-frequency (RF) sensing technologies, such as WiFi, Radio-Frequency Identification (RFID), and Frequency-Modulated Continuous Wave (FMCW) radar, have been utilized for non-invasive human activity recognition (HAR). It will be highly desirable to develop a HAR solution that can work with different types of RF technologies, such that the cost and the barrier of wide deployment can both be greatly reduced, and more robust performance can be achieved by utilizing the complementary RF sensory data. In this talk, we present a technology-agnostic approach for RF-based HAR, termed TARF, which works with several different RF sensing technologies. A novel data generalization technique is proposed to mitigate the disparity in measured data from different RF devices. A domain adversarial neural network is proposed to combat the interference from various RF sensing technologies. The performance of the proposed system is evaluated with experiments using four different RF sensing technologies. TARF is shown to outperform the state-of-the-art Convolutional Neural Network (CNN)-based solution with considerable gains.

Talent Promotion Program in 2015.
The contamination of images and videos are ubiquitous in storage, transmission, or manipulation of image data. One of central tasks in the field of image restoration is to recover clean ones from noisy data. Most existing image restoration methods assume observation models with random noise. However, structural degradation, such as bursty missing in transmission, frame loss in video capture, and the lack of high resolution information in undersampling, can also occur frequently in various vison applications. The simplified noise models would introduce mode mismatch and affect the overall restoration performance. In this talk, I am going to present our recent work in the field of image restoration, particularly some interesting investigation on restoration from moiré artifacts, which are much more difficult to handle than random noise.
